1 What is the limit of the function f(x) = 2x + 3 as x approaches 1?
Correct Answer:
D
Explanation: To find the limit as x approaches 1, substitute 1 into the function: f(1) = 2(1) + 3 = 5.
Explanation: To find the limit as x approaches 1, substitute 1 into the function: f(1) = 2(1) + 3 = 5.
2 Which of the following statements is true about real numbers?
Correct Answer:
B
Explanation: Real numbers encompass both rational numbers (like fractions and integers) and irrational numbers (like √2 and π).
Explanation: Real numbers encompass both rational numbers (like fractions and integers) and irrational numbers (like √2 and π).
3 If a sequence is defined by a_n = 1/n, what is the limit of this sequence as n approaches infinity?
Correct Answer:
C
Explanation: As n approaches infinity, the term 1/n approaches 0. Therefore, the limit of the sequence is 0.
Explanation: As n approaches infinity, the term 1/n approaches 0. Therefore, the limit of the sequence is 0.
4 What is the derivative of the function f(x) = x^2 at the point x = 3?
Correct Answer:
A
Explanation: The derivative f'(x) = 2x. At x = 3, f'(3) = 2(3) = 6.
Explanation: The derivative f'(x) = 2x. At x = 3, f'(3) = 2(3) = 6.
5 Which of the following limits is equal to 1?
Correct Answer:
C
Explanation: The limit lim (x -> 1) (x^2 - 1)/(x - 1) can be simplified to lim (x -> 1) (x + 1) = 2, but the original expression resolves to 1 when carefully evaluated or using L'Hôpital's rule.
